LWB front brakes on SWB

I was toying with the idea of changing my front brakes out for the larger LWB rotors. Has anyone done this and if so was it just the steering knuckle, rotors, calipers, pads? Wondering if the upper and lower control arms need to be changed as well.

i've done this on my 02 swb. the only difference are the rotors and the caliper brackets. everything else is the same.

Does it still fit inside the stock 16'' wheel? mine doesn't have much space. Seems like a bigger rotor/pad set up would be worth while.

I've looked at this swap as well due to it being a cost effective one but there is one question that I can't get out of my head... Unless the intent is to fill out a larger rim, why hassle for an extra 3/4" rotor diameter? You are using the same caliper and same size pads so in terms of stopping power any added grip strength would be marginal, no?

It moves the pads outward a bit so it does increase the leverage on the rotor. But yeah I do wonder how much of a difference it really is.

Different bracket = different pad size? :undecided:

The bracket is different, but the caliper and pads are the same.

IMO, GM wouldn't have changed them if it didn't help.

leverage is the only real reason. How big of a difference does it make, I dunno. I'm sure it could be calculated. Auto makers don't generally do anything just because. If they can do it cheaper they will. So I would assume it makes a difference. We could probably calculate it as percentage increase of leverage if we had measurements between the two.

Heat dissipation will also be better with the larger rotor.

I'm almost positive it will not fit with the 16" wheels. The calipers on yours are already hugging the inside of the wheel.

Cool, didn't think it was only a bracket change.

Now I need to figure what brakes to get. I don't think I will be going with the Akebono pro act this time, thinking on trying some EBC Ultimax or maybe the Yellowstuff, their slotted and dimpled rotors seem nice but at about $350 a pair that's pretty steep. I don't mind the dust or the fact I need to change them every 40K...just don't want them to squeal but bite when they are cold.

Not a huge fan of yellow colored brake pads :crazy: but if they work then that's fine.

Correct, Need at least 17" wheels

as to whether it helps, well, it can't hurt. the only reason i did it is because i ordered a set of reman'ed calipers and they sent me ext brakes. so instead of sending them back, I bought rotors to go with it. If you can score a set of brackets for a reasonable price, and if you need new rotors anyway, and aren't running 16" wheels, then why not?

My local parts store has the brackets, one side in stock but a few days on the other...no worries, I can wait.

Price difference was substantial over the dealer, naturally but I hope it's not made of tin foil. :undecided:
